Motor rotor and motor having same

Abstract

Disclosed is a motor rotor, comprising an iron core (10) and permanent magnets (20) provided inside the iron core (10). The iron core (10) is provided with sets of mounting grooves (30) on the iron core (10) in the peripheral direction of the iron core, each set of mounting grooves (30) comprising two or more mounting grooves (30) provided intermittently in the radial direction of the iron core (10). There are sets of permanent magnets (20), the individual permanent magnets (20) of each set of permanent magnets (20) correspondingly being embedded into the individual mounting grooves (30) of each set of mounting grooves; there is an island region (12) between the outermost layer of mounting grooves (30) and the periphery of the iron core (10), and an enhancing hole (13) is provided in the island region (12), an enhancing rod (60) being provided in the enhancing hole (13). Disclosed is a motor, comprising a motor stator (50) and the above-mentioned motor rotor, with the motor rotor provided inside the motor stator (50). The motor rotor enhances the structural strength of the whole rotor and improves the performance of the motor.
